          <title>Objective</title>
          <p>To determine the frequency of visual impairment in Idiopathic Intracranial Hypertension (IIH)</p>
        </sec>
        <sec>
          <title>Methodology</title>
          <p>A descriptive Cross-Sectional study was undertaken at the Department of Neurology, Mayo Hospital, Lahore, Pakistan from June 2023 to November 2023. After attaining IRB approval and informed consent from the patients, eligibility criteria were met and 129 patients were included in the study. A pre-designed form was used to document their clinical history and demographic information. Visual impairment was defined as the presence of any of the following: (a) blurring of vision, (b) diplopia, (c) reduced vision, or (d) compromised color vision.</p>
        </sec>
        <sec>
          <title>Results</title>
          <p>The mean age of the patients was 32.98 ± 9.62 years. Out of the total, 32 patients (24.81%) were male, while 97 (75.19%) were female. There was decreased vision in 84 (65.1%) patients, diplopia in 64 (49.6%) patients, impaired color vision in 98 (76%) patients, and blurred vision was noted in 77(59.7%) patients. The data analysis found no evidence linking obesity to a higher occurrence of visual impairment. Furthermore, no correlation between gender and the frequency of visual impairment was observed.</p>
        </sec>
        <sec>
          <title>Conclusion</title>
          <p>Impaired color vision was the most prevalent visual impairment, occurring in 76% of the individuals, followed by decreased vision, blurring of vision and diplopia in order of occurrence in patients with IIH.</p>
